Hi I'm a girl in year 12 and I basically just want to meet some guys. I know some in my lessons and through mutual friends, but none that think about me remotely romantically. I'm under no impression that it's my right to have a boyfriend, but I'd like to at least have a chance. How do I meet guys / get them to like me?

Be natural and chill. It's better to be in a relationship where both lovers love each other on the basis of their personality, and not a modified version of their personality on the premise of satisfying each other. If you want, start talking more, socialise more, add them on social platforms, have fun together, go out! There's no real way of getting 'boys to like you', because all boys are different....
